LIQUID-APPLYING DEVICE.

Specification of Letters Patent.

Patented Mar. 17, i914.

To all volw/m, it may concern Be it known that I, Mormnr. FRANK linooxn, a citizen of the United States, residing at Lawrence, in the county oit Essex and Commonwealth of Massachusetts, have invented certain Improvements in Liquidpplying Devices, of which the :following descxi'iiption, in connection with the accompanyingr drawings, is a specification, like reterence characters on the dra-wings indicating like parts in the several figures.

This invention relates to a liquid applying;` device and is herein illustrated in connection with a brush :tor use in machines it'or applying cement to parts of boots and shoes.

It is customary to apply cement to the channels of the soles ot shoes by presenting Athe sole of the shoe to a rotating' member which carries a coating oi' cement. lt has been tound to be desirable to use a bristle brush the bristles of which are fastened in a holder et cheap material such as wood and to dis- Vlard the holder after the bristles have bccome worn rather than to make the holder ot a more expensive material. such as metal and to reiill the holder with new bristles. wooden holder, however. is liable to swell or warp on account of the action ot the liquid cement, and in order to provide for this characteristic it is desirable that the holder be loosely confined.

To this end the present invention comprises a hub, a cement applying' member oLt expansible material mounted thereon, means l'or loosely confining said member in place, and means '[or rotating said member. This and other features of the invention, including certain details of construction and combinations ot parts will be described in connection with an illustrated device and pointed out in the appended claims.

Referring now to the accompanyin drawines,-ll`ignre 1 a vertical sectional view taken transversely oit the axis of rotation oi a device in which the present invention is embodied.; Fig'. 2 is a vertical sectional view taken longitudinally of said axis, the rotary shaft beine; shown in full lines gi Fig'. 3 is a view similar to Fig. 2 but showing a modiiication.

Referring' first to Figs. 1 and 2 of the drawings, cement is supplied from any suitable reservoir or tank, from which it is led f by any convenient means, as a conduit l2 to the eement-applying` member which is mounted in such manner that a shoe or other article to be cemented may be conveniently presented thereto. The applyii'n;n member is herein shown as a circular brush preferably composed ot a series oi linots ot bristles but obviously any suitable material may be substituted lior the bristles, or any other means capable of performing' the required 'function may be employed. This brush is suitably secured to one end. ot a rotary sha'l't 1G conveniently located with respect to the opening :trom conduit l2. The preferred manner of constructing' the brush is to wire or otherwise secure the knots of bristles about the periphery of a body portion in the 'term et an annulus 1,8 which, as it is discarded when the bristles are worn out. is preferably oi some inexpensive material sueh as wood. Thus the acting portion ot the applying member has a support independent oi the rotating' hub 20 on which it is mounted. Although wood is a preferable selection for the material trom which annulus i8 is made, an objection thereto is that when, moist it will expand and i 's p, thus tendina to throw any device used 'tor scouring: it on hub 20 out oil. alinement which is undesirable in this machine. Therefore the annulus, it of wood or asimilar material. must be mounted so as to allow lor expansion. Tn the construction shown in Fins. l. and 2 the hub 20 is provided with suitable devices, preterably situated adjacent the cement-applyinp.r member. for securing; said member against lateral displacement, here shown as a pair of flanges 22 and 24. The inner ilane'e 22 is preferably cast integral with the hub, the outer flange 24k beine' made removable theretrom. Flange 22 is provided with a peripheral lip 23 adapted to overlap annulus i8 and brine' the flange edec nearer the brush. its peripheral 'Face beine preferably beveled as shown at 25. Flange. is provided with a peripheral lip and beveled 'tace in a similar manner to flange 22. l-Tnb 20 is provided with an annular rabbet 2li in which flange 24 rests. abutting against the shoulder formed thereby. The hub 2O is so proportioned that the distance from the inner face of flange 22 to the shoulder lormed by the rabbet 26 is slightly greater than the width o'f annulus 18. With this construction. althourrh the annulus is held securely in place, suiHcient space is left between the inner faces of the flanges and the side of the annulus to allow for the expansion or warping of the latter when a material in which this is likely to occur is used. Any convenient means may be used to prevent rotation of annulns 18 on hub Q0, an eflicient arrangement comprising a slot or groove 19 in the annulus adapted to register with a pin 28 passed radially through lip 23 of flange 22. The assembled hub and brush are secured to shaft 16 in any convenient manner as by a locking screw 30 threaded into the end of said shaft and holding the hub between collars 32 and 3a on tie shaft and screw respectively.

The construction of Fig. 8 is similar to that of Fig. 2 in all respects with the exception that rabbet 26 on hub 20 is provided with screwthreads 27, removable flange 24 being also screw-threaded as at 29, the two itting together. It is thus seen that flange 24 may be screwed up tight against annulus 18', when said annulus is composed of moisture-prooi1 material, and then locked in position, or it may be adjusted so as to allow for a slight clearance when the annulus is composed of wood or a similar material.

Although the invention has been set forth in connection with a machine for applying cement to shoes it should be understood that this has been done for purposes of illustration only, and that the invention is not limited in the scope of its application to the particular machine shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States:

1. In a cementing machine, a hub, a ce-V plates for loosely coniining said holder in Y place and means for connecting said holder with one of said plates to cause it to be rotated therewith.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
